Question

A car racer accelerates uniformly to a velocity of 135 m/s over a distance of 412 m. Determine the acceleration of the car.

Answer 1

22.1 m/s²

Step-by-step explanation:

Given:

v₀ = 0 m/s

v = 135 m/s

Δx = 412 m

Find: a

v² = v₀² + 2aΔx

(135 m/s)² = (0 m/s)² + 2a (412 m)

a = 22.1 m/s²
